Thank you Mark!

My guages came in and I have 12-13 mmHg at the pump and 10psi at the filter (fully backwashed). I would not have thought that my TDH was so low (~36') but lucky me. My PB must have used parallel 1.5" throughout given my pump is so far from my pool. Using some online tools to size a pump for my...

After duraleigh's "long, long time for ROI" comment, I went back into mas985's pump spreadsheet and plugged $0 into the Equipment Cost to compare my current pump to the one I considered ordering for $350. At $0.11/kwh, it will take me ~6months to see an ROI and reap the benefits of a new pump...

@morzh: Yes, I was referring to permanent magnet motors. I knew a 2 speed motor would offer a certain level of energy efficiency, a PMM would offer even greater power savings. My research on this site shows that "typically", only a Variable Speed motors will be equipped with PMM so I've opted...

Thank you very much. I've been on a steep learning curve with my first pool and I appreciate all of your advice. I'm plumbed w/ 1.5" pvc throughout; 2 skimmers, 2 eyeball returns, 1 polaris jet from booster pump. I've decided that it would be best to use gauges to determine my THD to determine...

I just bought my home and am renovating it to be energy efficient (which my pool equip is NOT). I'd like to remedy this with a new pool pump and I'd like to request assistance with my logic. From what I've researched, I should size my pump at (30Kgal/8hr)=3750g/hr or 62.5g/min flow to exchange...
